CANCUN, Mexico (AP) — Hurricane Delta emerged into the Gulf of Mexico on Wednesday and headed toward Louisiana after making landfall just south of the Mexican resort of Cancun, toppling trees and cutting power to residents of the Yucatan peninsula’s resort-studded coast.

The U.S. National Hurricane Center in Miami said Delta had weakened to a Category 1 storm by late afternoon, with maximum sustained winds of 85 mph, but it was expected to gain strengthen again before lashing the U.S. Gulf coast. It was centered about 55 miles north-northeast of Puerto Progreso, just off the northern edge of the peninsula,and heading northwest at 17 mph.

Delta could make landfall, possibly as a Category 3 storm, sometime Friday south of Morgan City, Louisiana.

The hurricane came ashore in Mexico around 5:30 a.m. Wednesday with top winds of 110 mph. Officials said it caused no deaths or injuries, but did force hundreds of tourists to take refuge in storm shelters. It knocked out power to about 266,000 customers, or about one-third of the total on the Yucatan peninsula.

There were no reports of any deaths or injuries, said Carlos Joaquín González, the governor of the state of Quintana Roo.

“Fortunately, the most dangerous part of the hurricane has passed,” Joaquín González said, noting the big problem was downed trees that had knocked out power lines and blocked roadways.

Civil defense official Luís Alberto Ortega Vázquez said about 39,000 people had been evacuated in the states of Quintana Roo and Yucatan, and that about 2,700 people had taken refuge in storm shelters in the two states. Joaquín González said some tourists who had to take refuge at storm shelters had not yet been allowed to return to their hotels, where cleanup was underway, but said he hoped they would be able to by the end of the day.

There were reports of some flooding in Cozumel and Playa del Carmen. Overnight emergency calls came in from people whose windows or doors were broken and they were taken to shelters, he said.

Early Wednesday, guests of the Fiesta Americana Condesa hotel awoke in the sweltering classrooms of the Technological Institute of Cancun campus where they had been moved Tuesday.

All of the windows at the campus had been covered with plywood so they couldn’t see what was happening, but they said the howling winds started around 2 a.m. and there had been heavy rain. The power — and with it the air conditioning — had been knocked out early Wednesday so it was steamy as tourists used their cell phone light to get up and make their way for a first cup of coffee.

By early afternoon they were returned to their hotel and the state announced that businesses could reopen at 3 p.m. and the ban on alcohol sales was lifted.

“The hard part has been the waiting,” said Ana Karen Rodríguez of Monterrey. She and a friend arrived in Cancun Tuesday morning and by afternoon were shuttled to the shelter. She said the hotel had planned well. “It’s been good. I feel comfortable actually.”
